YARN CLEARER.

Application filed December ject of the invention is to provide a device of this character which'is capable of eilectuany clearing the thread or yarnoi gents, particles of libre, leaf, and other extraneous matter.

A further and more specitic object is to provide ayarn clearer which is readily adjustable so as to be capableo'l? operatn'ig upon yarns otvarying; sizes; which highly sensitive; and which operable autoniiactically to break the thread in the event an enlargement or foreign particle thereon attempts to pass through the device.

lily in'iproved yarn clearer is adapted for use with arious :torms oit spoolers and winders, but is especially adapted for use in connection with an automatic Winder of the type disclosed in the Colman Patents Nos. 1,267,977 and1.274,386 anted May 28, 1918 and August 6, 1918, respectively. In said patents there is shown a Winder equipped with bobbin holders oil the side 31, 1923. seri No. 683,571.

delivery type wherein the bobbin is revolved as the yarn is unwound. Said inder is alsoprovided vith a cam bar which is arranged to operate upon the clearing device in a manner which will hereina'lter appear. I

My ii'nproved yarn clearer when constructed in accordance with the present disclosure, comprises a pair of overlapping n'ie inbers or plates providing opposed parallel surfaces between \vhichthe thread to be cleared is passed, in combination with means for positioning the-thread-between saidsurfaces and a controlling i'nechanisn'l for the plates adaptedto varythe distance between said surfaces. Two plate men'ibers providing the opposed parallel surfaces are designated respectively 10 and 11 in the drawings (Figs. 5 and i are mounted so to be su'ingable on horizontal axes and are adapted to slide relative to each other in suchswinging movement. The member 10 is mounted to turn on a tubular member 12 which is mounted in a pair of spaced parallel vertical standards 13 (Fig. 4-). The member 11 is journalled upon a pin 14- arranged' eecentrically with respect to a shatt15 which in turn is journaled in the tube 12. t will be observed that the plates 10 and 11 are thus mounted to swing on parallel axes spaced ashort' distance apart. F or holding the two plate members in sliding relation one of the mem hers (herein the member 10) is provided at opposite edges with hooked flanges 16 torm- Jng ways in which the opposite edges oil The respective members are preterabl. I formed of sheet metal and their rear edges are bentupon themselves to form bearings 10 and 11" (Fig. 8) adapted to receive respectively the tubelQ and the pin 14L. To permit the member 11 to be mounted Within the tube 12, the latter is cut away upon its forward side as shown at 17 (Fig. 8), and the bearing portion 10 or" the member 10 is slotted loi' gitudinally at its forward side, as

shown at 18. s i

The member 11 in the present instance projects beyond the tiorivard edge off the member 10 a substantial distance, and adja cent the for vard edge of said member 10 is provided with a slot 19 open at one end. The forward Wall 20 0'1? this slot eons-:titutes 8) These members no the other plate member are adapted to slide.-

til)

one of the two opposed parallel surfaces of the clearing device, the other one of said surfaces being formed by the forward edge 21 of the member 10. If desired, the pin 1 1 maybe in the form of a screw (Fig. (5) threaded into anopening located eccentrically in the end of the shaft 15. Theserew has a head 22 atits outer or free end to re tain the bearing member 11 in position.

The means for guiding the thread a into position between the opposed surfaces 20 and 21 of the clearing members may be of any suitable character. Herein it comprises a pair of vertically spaced plates and 24: secured upon the upper and lower sides respectively of a block 25. These plates are extended beyond the right hand end of the block to form guide members 26 and 27. The upper one of these members 26 has a curved guiding surface 28 (Fig. 1), and the lower one of the members has a forwardly opening slot 29 the rear end wall of which providesa guiding surface 30. The rear edge of the upper. member 26 011 the other hand, provides an opposed guiding surface 31 (see Fig. 3). It will be seen by reference to Fig. 4 that a thread entering the slot 29 will be guided rearwardly around the member 26 by the curved surface 528, when it will spring into position between the opposed surfaces PiO and 31. Preferably the forward end of the member 11 is shaped like the guide member 26 to provide a rearwardly curving guide surface which assists in positioning the thread between the opposed surfaces 20-.-21 of the clearing device. As shown clearly in Figs. 1 and 5, the rear wall of the slot 19 is longer than the forward wall thereof, thus providing a portion 32 which serves as a stop to limit rearward movement of the thread when the latter is moving laterally into place in the slot 19. The member l'l has at its forward edge -a depending stop member 33 which is adapted to engage with the upper surface of the plate 23 so as to hold the members and 11 in approximately horizontal position with the opposed surfaces 20, 21. separated.

The upright standards 11-5 in which is mounted the tube 12 may be integrally connected at their lower ends to form a U- shaped frame which is mounted upon a base composed of the plates 23 and 2st and their spacing block 25, the frame being secured to the base as by means of a screw 3% This frame in additionto providing a'support for the tube 12 carries a plurality of fingers 35 which constitute a grid against which the thread is pressed by means of one or more detector lingers 36 suitably mounted upon the winder. y a

To adjust the plate members 10 and 11, in order properly to spacethe surfaces 20, 21 apart in accordance with the size of yarn being wound, it is only necessary to turn the shaft which effects a relative slidilig movement between the plates. To enable the shaft 15 thus to be turned 1 provide at one end (Fig. i) a forwardly extending portion or crank arm 3'? which is held by means of a coiled torsion spring downwardly upon an adjustable stop screw 2-51) carried by the aforesaid ba-e of the device. One end of said spring 38 engages with one of the standards 13 of the frame and the other cud engages with the crank arm as shown clearly in Figs. 1 and 1.

As aforesaid, the plate members ll) and 11. of the clearing device are held in approximately horzontal position by means of the stop member :33 ro ting upon the upper surface of the plate 223, and it will be apparent that upon rotation of the shaft in a countercloclnvise direction (Fig. 5), the plate member 11 will be drawn rearwardly by reason of its eccentric mounting upon the shaft, relative to the member 10. The result is a lessening of the distance between the opposed guiding surfaces and .21. Conversely, a reverse rotation of the shaft 15 tends to increase the distance between the opposed surfaces 20, 21. Prefe ably the plate 11 is downwardly client at the slot 15 so as to position the surface "l0 opposite the surface 21 in the plate 10; and to enable the said surfaces to be drawn together, the forward edge of the plate 10 is beveled as shown at at) to receive thedowmwirdly inclincd portion formed by the offset at the end of the slot 19 in the plate 11.

Normally the surfaces 20, 21 are spaced apart a distance sufficient only to. permit the thread to pass rhcrebetween without contact of the body of the thread withtho surliuur-l Q0, 21, any particles of foreign matter upon, the thread being cleared therefrom by cngagement with the plate members 10 and 11. at their respective surfaces so and iii. llut it sometimes happens that an irrel'uovablo enlargement or the like on the thread (see b Fig. 9) may attempt to pass; through the clearer, in which event. the engagement of the enlargement with the relatively light plates 10 and ii will arry them upwardly into the position shown in Fig. 9. in such movement of the plate-s, due to their eccentric mounting, the opposed surfaces 520, ill move together and clamp the thread, cans ing it to break under the teusi on due to rota tion of the yarn mass being formed.

As hereinbefore stated, the winder tender mechanism is equipped with a cum bar arranged to engage the crank arm ll? of the clearing device in the travel of said mccl'ianism so as to turn the shaft 15 in a clockwise direction, thus holdii'ig the opposrul surfaces 20, 21 apart so that the devim: can

readily be cleaned by a blast of air from the tender lllfiCllillllSlll. (ll'iviously when the dovice is used on a non automatic wmdcr or Ill.

Lemme spooler, the crank arm may be lifted manually to allow the accumulated clearings :to drop out and facilitate the cleaning operation.
